Hello!! My name is Kirby and I love sea creatures :)

I post a lot about marine biology. My favorite sea creatures are hammerhead sharks and nudibranchs!

My other interests are music (like every genre), audio equipment, classic literature, horror, Nintendo, Minecraft, and DIY/crafting.

Please feel free to send me asks! I’m also open to chatting in dms.

Camposcia retusa Latreille, 1829

Just a vague concept of a crab, materialised from the reef. Camposcia retusa is perhaps the most well known decorator crab species due to its popularity in aquarium trades. They're easy to recognize despite often being covered in all sorts of sessile organisms. When compared to other decorator crabs their unique proportion of long walking legs in relation to the rest of their body stands out as it's the characteristic body plan of the family Inachidae, while most other decorator crabs are members of families such as Epialtidae or Majidae. The name decorator crab is, unsurprisingly considering so many species are all referred to as such, not a conclusive name in phylogenetic terms. It can be referring to any species of crab that evolved to carry/house/attach sessile organisms or even detritus on their body. The majority of these species are under the Majoidea superfamily, the spider crabs, including our lovely Camposcia retusa. It's a highly diverse group of crabs and most decorator carbs are in this superfamily. Many of these independently evolved the behaviour and morphology to house organisms on their body surface, making the name decorator crab also a paraphyletic one. As a side note the name spider crab would be a much more descriptive name for Majoidea decorator crabs as it helps place their relation and grouping with other crabs.

GRAAAGH! I'm so hungry and I can't catch anything! If only I had ampullae of Lorenzini to help me sense where my prey is. Hey... You wouldn't happen to have some, would you?

Grammistes sexlineatus Thunberg, 1792

Grammistes sexlineatus, or the golden soapfish is a toxin producing fish closely related to groupers(used to be placed in the same family, Serranidae. Now in its own family, the Grammastidae.) These guys have a blasting radius with their anxiety attack(a literal attack!). While not enough to cause harm to humans, the toxic grammistin secreted from a soapfish's skin when stressed is used to deter predators and can even kill other fish when kept in captivity. That last part I always see mentioned in literature regarding soapfish, seems to me that some early ichthyologist had an unpleasant experience when trying to keep one as a pet… Grammistin has a slimy consistency and even tastes bitter(who's out here licking soapfish???) which is the reason for their common name.

If anyone's feeling sad today, here's a newly discovered species of octopus. Found in the waters off the Galapagos Islands, this little critter can fit in the palm of your hand.
